Back in commit [1], a patch fixing an issue a PowerPC issue in gcc was
added in gcc 4.3.3. It was present until gcc 4.9, which itself was
removed in [2]. The patch was dropped starting gcc 5.1 [3] but it's
know to be useful for gcc 4.7.3 [4]. However, even though we no longer
support building any of those older gcc versions, the conditional
patching logic in gcc.mk is still there.
We used to have a patch directory (package/gcc/$(GCC_VERSION)) for
every gcc version available in Buildroot, the apply-patches.sh script
doesn't error out even if
1000-powerpc-link-with-math-lib.patch.conditional is missing.
But with gcc 10, we don't need (for the moment) to apply any patch, so
the patch directory doesn't exist. apply-patches.sh breaks the build
since the patch directory is missing:
Aborting. 'package/gcc/10.1.0' is not a directory.
Since we removed gcc 4.9 last year [2], we can safely remove this code.
Tested using qemu_ppc_virtex_ml507_defconfig.

When the csky cpu support was added [1], the gcc download url was selected
depending on the csky cpu architecture (BR2_csky) rather than the csky gcc
fork version (BR2_GCC_VERSION_CSKY)[2].
When adding gcc 9.x version [3], we forgot to update the condition in order
to use the url to the gcc csky fork only when BR2_GCC_VERSION_CSKY=y.
Due to this error, the toolchain build with the upstream gcc 9.x for csky
cpu is broken due a download error.
Fix this by using BR2_GCC_VERSION_CSKY instead of BR2_csky.

This patch extends the "copy extra GCC libraries to target" feature to
also work for internal toolchains. The variable has been renamed to be
BR2_TOOLCHAIN_EXTRA_LIBS and the configuration option moved under the
generic toolchain package. For external toolchains, the step that does
the copy is still in the copy_toolchain_lib_root() helper which copies
from the sysroot to the target. For the internal toolchain, the host
gcc-final package does a post install hook to copy the libraries from
the toolchain build folders to both the sysroot and target(!static).
Examples where this can be useful is for adding debug libraries to the
target like the GCC libsanitizer (libasan/liblsan/...).

To simplify things, we make the whole C-SKY architecture require gcc-9

the C-SKY port.
Note that this does not change the default gcc version to be used for
C-SKY: the C-SKY port is still always the default one; the gcc-9 version
is only proposed as an alternative (except for ck610, of course).

This is a backport of upstream fix [1] for GCC's BUG #89838 [2].
The fix is the same as the one already merged for arc-2019.03 [3].
With the update of GCC to 9.2.0, this patch won't be needed anymore:
it's already merged in both the stable "gcc-9-branch" branch and the
"master" branch.
